Abstract: The present invention relates to a method for dyeing hair fibres, in particular a method which involves coating hair fibres with a hair dye composition and directing radio frequency electromagnetic radiation to the coated hair fibres to cause heating within the coated hair fibres by dielectric loss. The present invention also relates to kits and appliances for use in connection with the method, as well as the use of radio frequency electromagnetic radiation in reducing the effective dye-treatment time for hair fibres. In one aspect, there is provided a method of dyeing hair fibres, said method comprising the steps of: i) coating one or more hair fibres with a hair dye composition; and ii) directing radio frequency electromagnetic radiation having one or more frequencies from 1 MHz to 300 MHz to the one or more coated hair fibres to cause heating within the one or more coated hair fibres by dielectric loss.

Abstract: Topical compositions for treating hair are presented. The compositions comprise functionalized silicones having defined physicochemical properties that exhibit superior conditioning duability on hair than previously known silicone based conditioners, especially where the hair has been previously damaged through chemical treatments, such as occurs during permanent dyeing, bleaching and permanent waving.

Abstract: The present invention relates to a fiber or hair fiber conditioning treatment composition comprising a functionalised aminosilicone polymer and preferably in combination with a non functional aminosilicone polymer to provide improved conditioning without over conditioning negatives.

Abstract: The present invention is a method of pre-treating keratinous fibres prior to the application of a hair colourant or bleaching composition comprising the steps of applying a pre-treatment composition to the keratinous fibres said composition comprising at least one conditioning agent, said composition having a viscosity of from 100 Pa cps to 300 Pa, wherein said pre-treatment composition is not rinsed off from the hair prior to the application of said hair colouring or bleaching composition.

Abstract: The present invention relates to the field of hair care. More specifically, the present invention relates to the conditioning of hair after it has been oxidised in a coloring, bleaching or perming treatment. Superior conditioning is obtained by providing a cationic polymer to the hair while it is subjected to the oxidising treatment, and then the oxidised hair is subjected to a conditioning treatment with a composition comprising a functionalized silicone.
